Question

What controls the filtration medium resistance?

(a) Pressure drop alone

(b) Flow rate alone

(c) Both pressure drop and flow rate

(d) Cake thickness

The question was posed to me in a national level competition.

I need to ask this question from Filtering Medium Resistance topic in division Filtration of Food Processing Unit Operations

Answer 1

The correct choice is (c) Both pressure drop and flow rate

The best I can explain: Both pressure drop and flow rate controls the resistance due to the solid particles which forms the cake and also the filter medium. It also resists the influence of the force due to pressure difference across the filter medium.
